ASUS M6800N: problem when removing 'ac' module

ASUS M6800N: problem when removing 'ac' module

Hello,

I'm on '2.6.5-rc1 + ACPI DSDT in initrd + eciadsl USB patch' and I get this
message when I 'rmmod ac' or 'modprobe -r ac':
=====
Badness in remove_proc_entry at fs/proc/generic.c:664

and the AC state in the 'GNOME Battery Applet' isn't updated (it still shows I'm
on AC mode).

Please let me know if I should post in the kernel bug database.

Thx, bye,
